THEODORE BURNS, OF CLAYTON, INDIANA.

CULTIVATOR ATTACHMENT.

Application filed October 18, 1922.

To all whom it may concern.

Be it known that I, THEODORE BURNS, a citizen of the United States,residing at Clayton, in the county of Hendricks and State of Indiana,have invented new and useful Improvements in Cultivator Attachments, ofwhich the following is a specification. I

This invention relates to cultivator attachments, in the nature of aleveller, made up of two identically constructed relatively adjustablemembers, between which a plurality of teeth are supported, in the mannerto permit the teeth to be spaced different dis tances apart, theattachment in its entirety being adjustable to accommodate itself to anytype of cultivator.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawing, the invention residing in the construction,combination, and arrangement of parts as claimed.

In the drawing forming part of this ap plication, like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is a fragmentary view of a cultivator, showing the attachmentassociated therewith.

Figure 2 is a detailed view of one of the members of the attachment.

dicated at 10 and 11 respectively, and these bars are arranged in spacedparallel relation as shown. Each bar has one end extended to provide avertically disposed portion 12, the latter terminating to provide anattaching portion 13 which is secured to the cultivator by means ofU-bolts 14 which straddle said parts, and held associated therewith bymeans of a plate 15, which re- Serial No. 595,310.

ceives the ends of the U-bolts, which ends also accommodate nuts 16. Thebars 10 and 11 are adjustable longitudinally with respect to each other,so that the attachment can be varied in size to accommodate itself toany make of cultivator. Arranged between the bars 10 and 11 are teeth 17which are held in position by means of U-bolts 18 which straddle theparts in the manner illustrated in Figure 3. Each of these bolts haveassociated therewith a plate 20 and nuts 21, and which when tightenedhold the parts fixed relatively. It is manifest that when the size ofthe attachment is varied, incident to the longitudinal adjustment of thebars 10 and 11, that the teeth may also be spaced different distancesapart, and the distance between the teeth may also be varied withoutchanging the size of the attachment. \Vith the attachment associatedwith the cultivator it is particularly useful in the capacity of aleveller and pulverizer.

In Figures 4 to 8 inclusive, I have illustrated the use of a reinforcingor bracing element which is designed to prevent turning, or relativemovement of the teeth with respect to the bars 10 and 11 respectively.

- This element is clearly shown in Figure 7 and consists of an elongatedplate 22 from the diagonal corners of which project lugs or fingers 23.This plate is arranged at one side of the adjacent bar 11 as shown inFigure 4, and arranged parallel with the tooth 17. The lugs or fingers23 are arranged above and below the longitudinal edges of the bar 11extending inthe same direction, and also arranged at the opposite sidesof the tooth 17. This construction prevents the tooth from turning ortwisting, and in fact, eliminates all lateral movement of the tooth withrespect to the parallel bars. The plate 22 is held in proper position bymeans of the U-bolts 18.

While it is believed that from the foregoing description, the nature andadvanhaving an offset extremity, means for clamp- 10 ing said olfsetextremity to the cultivator, teeth arranged between the said spaced barsand capable of being arranged difierent distances apart, and means forclamping the teeth and bars together to hold the parts 15 fixedrelatively.

In testimony whereof I aflix my signature.

THEODORE BURNS.
